Texas Instruments – Optimized serial interface miniature micro-power SAR ADC

Texas Instruments (TI) has introduced the ADS8339, a 16-bit, 250kSPS analog-to-digital converter (ADC). The device operates with a 2.25V to 5.5V external reference and includes a capacitor-based successive-approximation register (SAR) and an inherent sample-and-hold circuit. The ADC includes a 25MHz, SPI-compatible serial interface which is designed to support daisy-chaining or cascading of multiple devices. The device is optimized for low-power operation and power consumption scales directly with speed. This feature makes the device attractive for lower speed applications. The ADS8339 is available in a VSSOP-10 package.
